| Abstract | ||
| The experimental works have been designed and implemented for testing the filters used in image processing .The coherent low pass filter using pinhole apertures of different sizes. two types of transparencies were prepared by computer (as objects), a text printed on black background and a text printed on thermal paper. The computer simulation on matlab were developed in this work. The coherent low pass filter . The results show a dramatic agreement between the experimental and theoretical work. The size of the effective pinhole on the filtered images were (0.25-0.5 mm). The best size was 0.5mm sizes. | ||
